| Topic | Rule (plain English) | Statute | Status |
|---|---|---|---|
| Security deposit cap | Tenants under 62: no more than 2 months' rent. Tenants 62 or older: no more than 1 month's rent. If a tenant turns 62 after paying more, refund the excess on request. | Conn. Gen. Stat. § 47a-21(b) | Verified |
| Deposit return deadline | Within 21 days after the tenancy ends, or 15 days after receiving the tenant's written forwarding address if later, return the deposit plus accrued interest. If you deduct damages, include a written itemized statement. Violations cost twice the deposit. | Conn. Gen. Stat. § 47a-21(d)(2) | Verified |
| Deposit holding and interest | Put deposits immediately into an escrow account at a Connecticut financial institution. Within 30 days, tell the tenant in writing the amount held and the institution's name and address. Pay interest at no less than the state deposit index, annually on the tenancy anniversary or as a credit on rent, and within 21 days after the tenancy ends. | Conn. Gen. Stat. § 47a-21(h)–(i) | Verified |
| Late fee cap and grace period | Grace period: 9 days (4 days for week-to-week), plus 5 more days if your online payment system prevents on-time payment. After the grace period, and only if the lease has a valid written late-charge clause, you may charge one late charge per payment. It may not exceed the lesser of $5 a day (maximum $50) or 5% of the delinquent rent (or of the tenant's share, if rent is subsidized). | Conn. Gen. Stat. § 47a-15a | Verified |
| Landlord entry notice | Give reasonable written or oral notice and enter only at reasonable times, except in an emergency. The statute sets no specific number of hours. | Conn. Gen. Stat. § 47a-16 | Verified |
| Rent increase notice | Give written notice at least 45 days before an increase takes effect. For leases of one month or less, give notice equal to one full term. A tenant's silence is not agreement, and rent can't be raised during a lease term. | Conn. Gen. Stat. § 47a-4e | Verified |
| Rent control status | Connecticut has no state rent cap. Towns with 25,000 or more residents must create, or join, a fair rent commission, which hears complaints about rental charges in order to control and eliminate excessive rents. Smaller towns may create one too. | Conn. Gen. Stat. § 7-148b | Verified |
| Eviction notice: nonpayment | Rent must be unpaid past the grace period: 9 days, or 4 days for week-to-week. Then you may serve a written notice to quit at least 3 days before the date to vacate, using the statutory form. | Conn. Gen. Stat. §§ 47a-15a, 47a-23 | Verified |
| Eviction notice: lease violation | For a material lease or rule violation, give a written notice specifying the breach, with termination at least 15 days after receipt. If the breach can be fixed by repair or by paying damages and the tenant does so within that time, the tenancy continues. If substantially the same breach recurs within 6 months, you may proceed to a notice to quit. Serious nuisance and nonpayment go straight to a notice to quit. | Conn. Gen. Stat. §§ 47a-15, 47a-23 | Verified |
| Required disclosures | Before move-in, give written notice of the name and address of the manager and of the person authorized to receive notices and service (§ 47a-6). Within 30 days of receiving a deposit, give notice of where it's held (§ 47a-21(h)(4)). Since April 1, 2026, every written lease must have the state's standardized rental terms summary form as its first page. Advertised rent must include all mandatory recurring fees (§ 47a-7d). For pre-1978 housing, give the federal lead-paint disclosure (40 CFR 745.113). | Conn. Gen. Stat. §§ 47a-6, 47a-21(h)(4), 47a-7d; 40 CFR 745.113 | Verified |
| Fair housing beyond federal law | Connecticut adds: - creed - ancestry - gender identity or expression - marital status - age - lawful source of income - veteran status - status as a victim of domestic violence, sexual assault, or trafficking - sexual orientation and civil union status (§ 46a-81e) | Conn. Gen. Stat. §§ 46a-64c, 46a-81e | Verified |
